This wallpaper features a Mexican West Coast Rattlesnake. Rattlesnakes are venomous, and are born with fully functioning fangs that can inject venom. They can regulate the amount of venom given when biting. It is estimated that 7,000 - 8,000 people are bitten by venomous snakes in the United States every year. 72% of those bites are from rattlesnakes. Image by H. Krisp
